Question

我想解析从服务器收到的JSON数据。

这是我的代码：

Alamofire.request(url).responseJSON { response in
    let resCode = String(data: response.data!, encoding:String.Encoding.utf8) as String!
    print("res:\(String(describing: resCode))")
    //print("data:\(response.data!)")
    let data = resCode?.data(using: String.Encoding.utf8)
}

print res：

RES：可选（ “{\” 代码\ “：200，\” 数据\ “：{\” HDL \ “：[\” 81 \”，\ “87 \”，\ “65 \”，\ “72 \”，\ “81 \”，\ “51.23288 \”]，\ “LDL \”：[\ “128 \”，\ “107 \”，\ “150 \”，\ “116 \”，\ “168 \” \ “114.03974 \”]，\ “三\”：[\ “189 \”，\ “187 \”，\ “210 \”，\ “192 \”，\ “200 \”，\ “171.26027 \”]，\ “栏\”：[\ “218 \”，\ “203 \”，\ “225 \”，\ “213 \”，\ “280 \” \ “194.59934 \”]， \ “BMI \”：\ “21.8 \”，\ “21.8 \”，\ “21.5 \”，\ “21.8 \”，\ “22.1 \”，\ “25.28467 \”] \ “年度\”： [\ “2011-04-20 \”，\ “2012-04-03 \” \ “2013年6月13日\” \ “2014年5月26日\” \ “2016年6月8日\” ，\ “预测\”]}}“）

我想将每个数据存储在HDL，LDL，TRI，COL，BMI和YEAR数组中。

您需要使用JSONSerialization方法jsonObject（with：data）将您的json数据转换为Dictionary：

let json = "{\"code\":200,\"data\":{\"hdl\":[\"81\",\"87\",\"65\",\"72\",\"81\",\"51.23288\"],\"ldl\":[\"128\",\"107\",\"150\",\"116\",\"168\",\"114.03974\"],\"tri\":[\"189\",\"187\",\"210\",\"192\",\"200\",\"171.26027\"],\"col\":[\"218\",\"203\",\"225\",\"213\",\"280\",\"194.59934\"],\"bmi\":[\"21.8\",\"21.8\",\"21.5\",\"21.8\",\"22.1\",\"25.28467\"],\"year\":[\"2011-04-20\",\"2012-04-03\",\"2013-06-13\",\"2014-05-26\",\"2016-06-08\",\"predict\"]}}"
let data =  Data(json.utf8)

if let dict = (try? JSONSerialization.jsonObject(with: data)) as? [String:Any],
    let subdict = dict["data"] as? [String:[String]] {
    let hdl = subdict["hdl"]    // ["81", "87", "65", "72", "81", "51.23288"]
    let ldl = subdict["ldl"]    // ["128", "107", "150", "116", "168", "114.03974"]
    let tri = subdict["tri"]    // ["189", "187", "210", "192", "200", "171.26027"]
    let col = subdict["col"]    // ["218", "203", "225", "213", "280", "194.59934"]
    let bmi = subdict["bmi"]    // ["21.8", "21.8", "21.5", "21.8", "22.1", "25.28467"]
    let year = subdict["year"]  // ["2011-04-20", "2012-04-03", "2013-06-13", "2014-05-26", "2016-06-08", "predict"]
}

Swift JSON解析为数组
